my gdp outdoors is getting some leaves that are starting to twist, the plants is very healthy and strong, bushing out real nice, just have some leaves twisting, any idea what this could be.
Use and worship this chart, you wont find it on any grow guide and it is not well known. This in my opinion nails down identifying cal/mag problems. Calcium deficiency on the left and magnesium deficiency on the right. Notice the purple stem for cal def and the green stem for mag deficiency. Cal/mag def would be a mixture of the both i guess.
